Prezi deleted my account;

Hi,

İ had an account, with this name, and a few prezis created online with it.

but, when i tried to log in a few weeks later my account has gone with all the prezis.

i tried to log in and it has not accepted my password, then i tried to recover my account tha said "unknown email". after that i re created the same account with the same user e-mail, but i cant find my prezis.. :(

now, how can i bring them back?

thanks, Ersin
